I personally chuckle when people suggest TLoU2 or Death Stranding could be launching in 2019... On the other hand I can definitely see Ghost of Tsushima happening. And if this Swedish retailer is to be believed then it will positioned in a similar healthy timeslot as Spider-Man last year for the run-up to the holidays.
Sucker Punch have historically been a timely developer that doesn't stray far off initial release target (and I presume that means delivering on budget). Ghost of Tsushima has now been in development for near twice the length of any of their previous projects, all the way since 2014...
Autumn 2019? I believe.
